change label text in asp.net

I'm trying to change label's text by using javascript:

<head runat="server">
    <script type="text/javascript">
        function updateLabel() {
            var lblElement = document.getElementbyId("Label2");
            lblElement.innerHtml("new");
        }
    </script>
</head>

I call this script from the code behind:

mainPage.ClientScript.RegisterStartupScript(GetType(), "MyKey", "updateLabel();",true);

It's not working...

Using a buildin trigger like button click won't work for me that's whyI'm trying to find a way to do it with javascript.

Javascript is CaSe SeNsItIvE, the property is innerHTML NOT innerHtml, and it is a property not a method so you need lblElement.innerHTML = "new";. Also unless you are running .NET 4 or later and have ClientIDMode="Static" in your @page directive you will have to take into account the actual ID that is rendered in the HTML:

<head runat="server">
    <script type="text/javascript">
        function updateLabel() {
            var lblElement = document.getElementbyId('<%=Label2.ClientID%>");
            lblElement.innerHTML = 'new';
        }
    </script>
</head>
